Spontaneous Breaking of Space-Time Symmetries

Understand

Kinematical and dynamical mechanisms leading to the spontaneous breaking of space-time symmetries are described.

• The symmetries affected are space and time translations, space rotations, scale and conformal transformations.
• Applications are made to solidification, string theory compactifications, the analysis of stable theories with no ground states, supersymmetry breaking and the determination of the value of the vacuum energy.
